Definitions
- the first bag body 10 surrounds the second bag body 20. Thereby, the dialysate solution W that flows out from the second interior of the second bag body 20 through the first filter 22 of the second bag body 20 can be stored in the first interior of the first bag body 10.
- the first bag body 10 may surround the second bag body 20 and the third bag body 30. Thereby, a solution, in which the first powdered pharmaceutical agent 1 is dissolved, may flow out through the first filter 22 to the third interior of the third bag body 30 where the second powdered pharmaceutical agent 2 is dissolved to produce the dialysate solution W, and then the dialysate solution W may be stored in the first interior of the first bag body 10.
- the shape of the first filter 22 is not limited to a three dimensional shape which is convex in the upward direction, and the first filter 22 may be of any shape that divides the flow of the jetted water RO into multiple directions of up, down, left, and right.
- the dialysate container 100A according to the second embodiment differs from the dialysate container 100 according to the first embodiment described above mainly in the points that that the first bag body 10 is replaced with the first bag body 10A, and the second bag body 20 and the third bag body 30 are provided at the exterior of the first bag body 10A.
- components which are the same as the components which were described above in the first embodiment may be denoted by the same reference numerals and descriptions thereof may be omitted.
- the first bag body 10A is flexible in a manner similar to that of the first bag body 10 of the first embodiment described above, it can be folded in any manner.
- the first bag body 10A can be folded back and folded at the positions indicated by the double dotted chain lines Z in FIG. 7 and be made into a compact shape. Therefore, the dialysis solution container 100A exhibits superior portability, is not bulky when transported or stored, and.is capable of saving space.
- An upper end of a first connection pipe 50 is connected to the lower portion of the buffer chamber 40.
- the lower side portion of the buffer chamber 40 is integrated (sealed) in a watertight manner by an appropriate means such as by being fused except for a location at which the first connection pipe 50 passes through.
- a joint portion which is capable of connecting with the upper end of the first connection pipe 50 may be integrated with the lower portion of the buffer chamber 40 instead of the upper end of the first connection pipe 50.
- the upper end 61 of the second connection pipe 60 is connected to the first connection pipe 50, and the lower end opens into the first interior of the first bag body 10A. It is preferable for the lower end of the second connection pipe 60 to be located in the vicinity of the bottom portion of the first interior of the first bag body 10A. In this case, it is possible for substantially all of the dialysate solution W (the produced dialysate W) which is formed in the first interior of the first bag body 10A to be discharged to the dialysis circuit at the exterior of the first bag body 10A via the transferred to the second connection pipe 60, the first connection pipe 50, the third bag body 30, the second bag 20, and the communication pipe 21. That is, the utilization efficiency of the produced dialysate W can be improved.
- the flexible second bag body 20 and the flexible third bag body 30 are utilized.
- the present disclosure is not limited to such a configuration.
- the second bag body 20 and/or the third bag body 30 may be partially or entirely inflexible.
- the second bag body 20 and the third bag body 30 may be formed by resin.
- the portion which is formed by the resin and the portions which are formed by the flexible material may be coupled by being fused, etc.
